A light-year is the distance that light travels in one year.
the speed of light is 299,792,458 metres per second which is about 670.6 million mph
Alpha Centtauri is 4.37 light years away so if you were to travel at the speed of light it would take you 4.37 years to get there from earth.
light travels 5,874,589,152,000 miles per year
The Challenger space shuttle was recorded as going about 18,000 mph. Which means it would travel 157,680,000 miles per year. that means for the challenger to travel one light year it would take 37,256 years for a man made machine to travel one light year.

How long does it take to travel 1 light year?
It will take 1 year, as soon as you and Albert work out how to travel at the speed of light. ;)
How much is 9.7 light years?
well it depends on what you are measuring your 'much' in. First thing is, a light year is a distance not a time. It is defined as the distance light would travel in the time of one human year. Now to define this: light travels at ~300000000ms-1 and there are 31536000s in one year, so light will travel: 300000000*31536000 = 9.5x1015 metres in one year (that is 95 followed by 14 zeros! so a long distance) so in 9.7 light years light will travel 9.2x1016 metres. Which is a very very long distance.
What is 980200000000000 in scientific notation?
95,000,000,000km/ph/lt/yrs is the speed of light. It takes light that long for light to travel to earth in about 1 light year. 95,000,000,000km/ph/lt/yrs is the speed of light. It takes light that long for light to travel to earth in about 1 light year.
How long is light years?
A light year is the distance that light can travel in a year.5,865,696,000,000 miles or 9,460,800,000,000 kilometresThis can be worked out because we know how far light travels in a second (186,000 miles per second / 300,000kilometers per second), we can therefore use simple maths to work out the answer.186,000 miles/second x 60 seconds/minute x 60 minutes/hour x 24 hours/day x 365 days/year = 5,865,696,000,000 miles/year.
How long does it take for gladwrap to decompose?
a year
How long does it take to travel 1 light year?
It will take 1 year, as soon as you and Albert work out how to travel at the speed of light. ;)
How long does it take for light to travel a distance of one light year?
Light travels a distance of one light year in one year.
How long does it take for a lightyear to travel?
A lightyear is the distance that light can travel in one year.
How long would it take 1400MHZ to travel 200 light years?
If you are talking about an electromagnetic wave, it will travel a light-year per year. That's how the "light-year" is defined. The frequency (1400 MHz) is irrelevant in this case.
How long in years to travel 1 ght year?
if you're asking "how long in years to travel 1 light year" you would have to know how fast you are traveling. a light year is a measure of distance that's equal to approximately six trillion miles...
How long in lightyears would it take to travel to Eris the dwarf planet?
A light year is a unit of space, not time. It is the distance light travels in a year. Eris is far less than a light year away.
How long would it take to travel 1 light year traveling 80 miles per hour?
It would take approximately 37,200 years to travel 1 light year at a speed of 80 miles per hour. This is because a light year is the distance that light can travel in one year in a vacuum, which is about 5.88 trillion miles. At 80 miles per hour, it would take a very long time to cover this immense distance.
How long in light years does it take light to travel from the sun to the earth?
Light takes about 8 minutes to travel from the sun to the earth.We have a misconception here, a light year is a unit of distance not time. This confusion is very common!
How long does it take for light years to travel around the earth once?
One light-year is the distance light travels in one year, which is about 5.88 trillion miles. Light doesn't orbit the Earth, but if you're asking how long it takes light to travel around the Earth's circumference once, at the speed of light (about 186,282 miles per second), it would take only about 0.13 seconds.
What is the approximate time it would take to travel a light year?
if you are going the speed of light, it would take 1 year.
How long would it take to travel only one light year?
What, walking, swimming? a long time. By definition one light year is how far LIGT travels in one year. That's 5.8 trillion miles, or 5,800,000,000,000!
How long would it take to neerest galaxy?
Canis Major at 25,000 light years away a light year is equal to the time it takes light in one year to travel. Speed of light is roughly 671,000,000 mph.
